Far higher resolution and pixel density leads to greater clarity and reduces the need for anti-aliasing.[2]

Modern graphics cards are finally powerful enough to achieve 4K resolution at smooth frame rates. A single GTX 1080 Ti can play many modern games at 4K at 60 FPS on ultra/maximum settings, and can even achieve 120+ FPS on most older titles up to about 2012 to 2013.[3]

Running games at this resolution requires a high-end rig - in 2013, achieving 60 FPS at max settings on Metro 2033 required four NVIDIA GTX Titans.[5]

Mainstream 4K displays are currently limited to a 60 Hz refresh rate. 4K monitors with a high 144 Hz refresh rate were released in mid 2018, but the initial retail price is extremely high ($2000 for 4K 144Hz including HDR and G-Sync).[6] Additionally, even very powerful modern systems are still not able to achieve anywhere near 144 FPS in 4K in the most recently released games.[7][8]. At the end of 2018, the only way to reliably achieve 100+ fps in most modern titles at 4k is with 2 2080 TI cards in NV Link SLI, which would cost approximately $2500 for the GPUs alone.[9]

4K support on Linux, especially at 60 Hz, can be spotty due to the varying quality of drivers and their ability to stitch together DisplayPort MST panels. hax11 attempts to work around similar issues by intercepting and editing X11 requests between games and the X server.
